Across
- 2. a material in which a wave travels
- 4. occurs when waves that overlap combine, forming a new wave
- 6. when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
- 7. is the passage of light through an object
- 9. makes the particles in a medium mobe parallel
- 12. is a wave in which the disturbance is perpendicular to the direction the wave travels
- 13. is the transfer of energy by a wave to the medium through which it travels
- 14. is a disturbance that transfers energy from one place to another without transferring matter
Down
- 1. is the change in direction of a wave that occurs as the wave changes speed when moving from one medium to another
- 3. a wave when it travels by the edge of an obstacle or through an opening
- 5. is the bouncing of a wave of a surface
- 8. a wave that can travel only through matter
- 10. the lowest points on a transverse wave
- 11. the highest points on a transverse wave
